LOCK.

SPECIFCATION forming part of Letters Patent No. 692,7 92, dated February 4, 1 902.

Application iiled September 28, 1901. Serial No. 76,920. (No model.)

To @ZZ whom it mln/ zj concern:

Be it known that I, CRAWFORD D. LOGAN, a citizen of the United States, residing at Coalhill, in the county of Johnson and State of Arkansas, have invented a new4 and useful Lock, of which the following is a specification.

The present invention relates to permutation-locks, and more particularly to that class set forth in a previous' patent granted to me on January 16, 1900, and numbered 641,458. In fact, this invention is designed as an improvement on the construction set forth in said patent, the object being to greatly simplify the structure without sacrificing any of the good features thereof, thereby providing a lock that is made of a minimum number of parts or elements which are of a simple nature and not liable to become deranged. In the former construction acatch was provided, locking means therefor, actuating mechanism for the locking means, and a cover for the actuating mechanism. An operating device was employed for the latch and a separate locking device for the cover.

One of the features of the present invention is to so reconstruct the mechanism that but one device is employed having both functions. Outside of simplifying the structure other advantages result from the arrangement which will more readily appear when the construction isv understood.

A further feature resides in simpler and more easily understood locking means.

In the accompanying drawings there is fully illustrated the preferred embodiment of the improved lock, and the construction and operation of the same are described in the folperspective View of the other tumbler; and Fig. 6 is a perspective view of the holdingdisk for the tumbler illustrated in Fig. 5.

Similar numerals of reference designate corresponding parts in allthe figures of the drawlngs.

The lock shown in the accompan ying drawings is applied to a hasp intended for locking trunks, chests, or any analogous receptacle usually employing a hasp. In order to show the application of the invention, therefore, a portion of such a receptacle is shown, the body-wall being designated 10 and the coacting cover-wall 1l. The hasp isdesignated as a whole by the reference numeral 12 and comprises a pair 'of hinged leaves, one of which, as 13, is secured to the Wall 11, while 'the other, 14, carries the'locking mechanism. -In the construction shown this mechanism is as follows: A sliding catch-bolt 15 is located upon the under face of the leaf 14, having at one end a retaining-finger 16 and at the other end an arm 17, that is adapted to fit inrecesses or notches 18 of rotary tumblers 19 and 20, located upon the under face of the leaf 14 when said notches are alined..

The 'tumbler-s are mounted and operated in vthe following manner: A sleeve 21 is rotatably mounted in an opening 22 in the leaf 14, said sleeve carrying on its outer end a collar 23, having a suitable indicatingscale 24, which is arranged to register with a scale 25 upon the outer face of the leaf. The sleeve is provided on its inner end with a tooth 26,

that is arranged to engage in one of a seriesof notches 27, arranged in the edge of a central opening 28 in the tumbler 19, Which opening receives the inner end ofthe sleeve.

Passing through the sleeveand rotatably mounted therein is a post 2,9, the outer end of which has 'a milled operating-head 30 and an annular flange 31, fitting in a seat 32 in the outer face of the collar 23. This flange is provided with an indicating-scale, as34, which coacts with the scale 24 of the collar. The opposite end of the post is angular in cross-section, and the tumbler 20 is rotatably mounted upon the inner end contiguous to this angular portion. A holding-disk 35 is detachably iitted upon the angular portion of IOO the post and is provided on its inner face with a pin 36, arranged to detachably engage in one of an annular series of openings 37 in the tumbler 20. A Washer 38 is secured to the post over the holding-disk by means of a screw 39, that is threaded into the end of the post. By this means it will be seen that the several tumblers are held on their respective operating devices by means of a single Washer and screw 38 and 39, but that each tumbler is capable of independent movement, and the combination may be changed by changing the relation of the notches 18 and the indicatingscales. A cylindrical boxing 40 normallyincloses the tumblers and is held in place by fastening-screws, as 4l.

The operation of the lock will be clear to those skilled in the art. Having first located the notches of the tumblers so that they will be in alinement when the scales are in a certain predetermined relation and said notches being also in alinement with the end of the arm 17 of the catch-bolt, it will be seen that said catch-bolt may be slid inwardly, and,vice versa, when the bolt is slid outwardly and the tumblers rotated until their respective notches are out of alinement the bolt will be locked against such inward movement. The locking-iinger 16 of the bolt is arranged when in its projected position to engage the holding-ledge 42 of a metallic casing 43, that is secured in a suitable opening made for the purpose in the body-wall l0, said casing being arranged to receive the tumbler mechanismandthecatch-bolt. In ordertoprotectthe actuating mechanism of the locking means, a cover or cap-plate 44 is hinged, as at 45, to the swinging leaf 14 and is provided witha pocket 46, that receives the projecting portions of said actuating mechanism. This cover is furthermore provided at its free end with a keyhole-opening 47.

The operating device for the catch-bolt 15 is in the form of astem 48, rotatably secured to said bolt and extending through a slot 49 in the leaf 14, which slot permits of the necessary sliding movement of the pin. The projecting end of the pin is provided with an enlarged circular head 50, having an offset locking-lug 51 at its upper edge. This head is arranged to t in the opening 47 of the swinging leaf, but with the lug 5l located above the same, so that by turning said head the lug will be out of alinement with the notch of the keyhole-opening, and thus hold the cap-plate in operative position over the actuating mechanism.

The operation of the device will be readily apparent. To unlock the hasp, the cap-plate is iirst thrown back to the position shown in Fig. 2 and the tumblers actuated in the manner above pointed out until the bolt is released. When this is accomplished, said bolt is thrown to its inner position, so that its locking-finger will disengage the holdingledge and the hasp may be raised. To relock est-)2,792

the device, the operation is reversed, after' which the cap-plate is swung down over the actuating mechanism and the head rotated until the lug is out of alinement With the slot of the keyhole. By this construction it will be seen that the operatin g mechanism is greatly simplitied, thus employing a fewer number of elements than in the former construction and aording a more compact structure. Further than this, however, the means for operating the bolt and locking the cover in place besides being much simpler is more readily understood. Furthermore,when the cap-plate is locked in place the circular head fitting snugly in the opening thereof will serve as an additional means for holding the bolt in projected position, and thus relieve the tumblers of a portion of any backward strain upon the bolt.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art Without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a hasp, of a catch for holding the hasp, locking means for the catch, actuating mechanism for the locking means, a cover removably fitting over the actuating mechanism, and an operating device for the catch, said device also constituting holding means that engage the cover to secure said cover over the actuating mechanism.
